This unit is a little hit or miss for me.
It is very easy to setup and I got it to sync with my Note 4 with no issues but there are a few software implementations that need to be addressed. #1 It doesn't always go back to the home screen, #2 there should be a way to turn off some of the notification options, meaning I would like to get the notification through the watch, however, I would not want to take the call through the watch.
Now I know that that is the point of the watch, but if I'm sitting with a group of people and I get a notification that there is a call coming through and I would like to answer it without using the watch that is always on speaker, then I would like a notification of a call and answer it on the phone.
Other than that the watch works great it just needs some work on the software end.
